Social variation in reasons for contacting general practice out-of-hours: implications for daytime service provision?

Contact with general practice out-of-hours services increases with socioeconomic deprivation. The reasons for this association are unclear but may include variations in access to daytime services or differences in morbidity.

To identify the reasons for contact with the Glasgow Emergency Medical Service (GEMS) in relation to patient sociodemographic characteristics and the nature of the presenting problem.

All contacts with GEMS over a one-week period (n = 3193) in October 1996 were identified and a random 1:2 sample were sent a postal questionnaire investigating their reasons for contacting the service. Sociodemographic data and presenting problems were extracted from the service contact sheet. Data were analysed using correspondence analysis.

Correspondence analysis identified two factors characterised as 'perceived problems with daytime services' and 'perceived urgency'. Scores on the former dimension were significantly associated with age (P < 0.0001), gender (P < 0.0001), socioeconomic category (P < 0.0001), and presenting problem (P = 0.015) and scores were higher in adults, in males, among the non-affluent (particularly those resident in deprived areas), and in those presenting with a musculoskeletal problem. Scores on the latter dimension were significantly associated with age (P < 0.0001) and presenting problem (P < 0.0001). Scores tended to increase after childhood and for each of the five most frequent categories of presenting problem relative to other symptoms.

Compared to those from affluent areas, patients from non-affluent areas appear to perceive difficulties accessing their general practitioner during surgery hours and may contact out-of-hours services as an alternative.
